* This is an abstract to guide the developers in using this event name for their events.

32 |
* It is intended to be used when the user viewes the list of all the instances of a module

* Example:
|
|
|
36 |
*
|
|
|
37 |
* \mod_chat\event\course_module_instance_list_viewed extends \core\event\course_module_instance_list_viewed
